FSQ500N  
Green Mode Fairchild Power Switch (FPS™)  
Features  
Description  
The FSQ500N is specially designed for low cost, small  
set-top box, DSL, home appliance auxiliary power  
supplies. This device combines a current-mode Pulse

Single-Chip 700V SenseFET Power Switch  
Precision Fixed Operating Frequency: 130kHz  
Width Modulator (PWM) with  
a SenseFET. The  
No-Load Consumption 250mW at 265VAC with  
Burst Mode  
integrated PWM controller features include: a fixed  
oscillator, Under-Voltage Lockout (UVLO) protection,  
Overload Protection (OLP), Leading-Edge Blanking  
(LEB), an optimized gate turn-on/turn-off driver,  
Thermal Shutdown (TSD) protection with hysteresis,

Soft-Start Time Tuned by External Capacitor  
Under-Voltage Lockout (UVLO) with Hysteresis  
Pulse-by-Pulse Current Limit  
and  
temperature-compensated  
precision-current  
sources for loop compensation. When compared to a  
linear power supply, the FSQ500N reduces total size  
and weight, while increasing efficiency, productivity, and  
system reliability. This device provides a basic platform  
for cost-effective flyback converters.
